  This paper presents important findings into the response of epithelial monolayers to the combined effects of surface curvature and hydraulic stress, offering insights into how these cues contribute to epithelial cell extrusion. Most of the evidence is convincing, relying mainly on a combination of imaging-based techniques. This paper is of interest to a broad and growing community of biologists, biophysicists, and engineers interested in cell-geometry interactions.

  This important study provides novel strategies to overcome certain limitations when investigating the metabolism of hematopoietic stem cells, mainly due to their low abundance. The study provides compelling evidence suggesting that proliferative hematopoietic stem cells mainly use glycolysis (rather than mitochondrial OXPHOS or TCA cycle) as their primary energy source during emergency hematopoiesis. The article provides direct links between metabolic features and cell proliferation and explores alternative energy sources, and is of great interest to stem cell biologists.

  This fundamental study addresses a long-standing mystery in splicing regulation: does splicing occur co- or post-transcriptionally? The authors provide compelling evidence demonstrating that splicing can occur post-transcriptionally at a transcription site proximal zone, changing the way we think about splicing.

  This study presents a valuable finding on how the GAP DLC1, a deactivator of the small GTPase RhoA, regulates RhoA activity globally as well as at Focal Adhesions. Using a new acute optogenetic system coupled to a RhoA activity biosensor, the authors present solid evidence that DLC1 amplifies local Rho activity at Focal Adhesions. Nevertheless, the proposed mechanism could be further supported by a deeper analysis of the data.
